The last novel I read was "The Children of Men" by P.D. James. The central theme of the book is the loss of hope in a future generations due to a worldwide infertility crisis. The story follows a small group of rebels who mount a desperate campaign to save mankind. Each of the characters struggles to overcome the despair of their society, ultimately embracing the courage and determination to fight for a better future.
